IMPROVEMENT IN MACHINE PoR .eRINDINe THR oUTTRRs- 0I'IIIIOWINc-MAGIIINBS. A

To' ALL wHoMIT MAY coNoERN:

Be it known that we, HENRY F. PHILLIPS and HENRY `LEONARDofvAuburn, inthe county 'ol'Caynga, and State of New York, haveinventcdcertain newand useful Improvements in Macliinesfor Grinding Mowin'g andReaping-Machine Sections; and we do hereby declare the following to beafullclear, and exact description of the sama-reference being had to theaccompanying drawings, making a part of this specification, in which-j-Figure 1 represents an 'end elevation ot" the machine.

Figure 2 represents a side view of thc same.

`Figure 3 represents a top plan, and' i y Figure 4 represents a verticalsection, taken at the red line w of iig. 2.

Similar letters of reference, where they occur `in the'separate figures,denote like parts of the machine in all of the drawings. I

Our invention relates topa machine for grinding harvesting-'machinesections,` whereinthestone is fedup to the sections whilst the latter'is rigidly held, or in feeding up the sections whilst the stone isrigidly held; and it further relates to a rocking or rolling motiongiven to the frame, for adjusting thedp or inclination of' the stone, aswell as its sliding motion, to tix the position of thestoneyand itfurther relatesto th'e arrangement Afor holding-and controlling theknives`or sickles and their bar whilst being ground. i

` To enable others skilled inthe art to inake and use our invention, wewill proceed to describe the same with reference to the drawings.

On a bed, A, is arrangedda block, B, so that it may be movedgnided, andheld on said bed, it being moved -betwcen guides a a, and firmly held,when properly adjusted, by the screw-bolt b. On top of the block B, andin a rounded bed or bearing prepared thereon,is placed the yoke-0rbracket C, for forming'bearings c c for the shaft D of the grindstone Eto turn-in. Thisbracket orbearer C is held to the block B by thescrew-bolt 6, which passes through a slot, d, in the bracket, so thatthe bracket rnaybe inclined to give an inclination. or pitch to thegrindstone, when necessary to do so,v and when adjusted, it is firmlyheld by the lscrewfholt b. On tho shaft D there is a collar, e, which,when adjusted, is held to the shaftby a set or clamp-screw, f,'and in,the rear hearcrc there is a mortise, through which an arm, g, moves,the forward end ot'said arm being forked and straddling Ythe collar e ingroove, k, therein.. There is also o n the .arm g a mortisc, opening, orshoulder, c', in pr against which, and against the rear bearer e', awedge, 1c, (shown in dotted lines in fig. 3,)'is slipped, to force, andat the Vsaine time rigidly hold, the grinds'tone against the sections.This feeding up and holding ofthe stone 'against the sections, or cz'ceversa, prevents any vibrations which tend to wear the, stone out ofround, or from causing it to jump, when a -hard spot inthe stone strikesthe metal. On top of the rearbearer cf (and there, hy preference, simplyfor convcnience,) there is a'. set-screw7'.` -which can he run downagainst the arm g, so as -tohold said arm from moving, and in thusholding said armv the stone'or itsshafL-having no end motion allowed toit, will revolve in a fixed position. This arrangen'icnt is necessarywhen the grindstone is used (which it canhe) for any o f the ordinarypurposes of grinding. i

`In front of the grindstone, and upon the'hed A, there 'is a hollow hubor column, F, in which a spindle, l, onthe holder G, tits and mayturn,and in this hub or socket F there is a' ring-clamp, through which thespindle passes, and by which it'may be restrained in turning by anut,-m, run up on thc` thrcaded portion n of said ring-clamp. A p

Upon the top of the hub or column F,'and underneath the beareror holder`G, there isa plate, H, the outer ends of which, I I', are formed intoarcs, making a support or tablefor the holder -to rest upon. Onon'e ofthe arcs, I, there is an upright arm, o, adjustable thereon by a.set-screw, p, which passes-through a slot in the ae or table I, so as tobe set up more towards or from the stone, as the case may be.. I`n -thetop ofthisnpright arm dther'e is dect-screw, q, which bears against theback ot' the holder G, and keeps it in its properly-inclined position.In the holder, at or near the rim of the other arc or table, I',there-is a hook-headed bolt, r, which takes under the edge of the arcor' table, and' whilst it allows the holder to turn on its spindle, itprevents it from rising from the'tablc. l l

anios 2 In a recess, s, in the face, of the holder G, the baron whichthe knife-sections t to be ground. are fastened,

is placed, and clamped by hook-headed clamps, which are drawn up bythumb-nuts u u, on the rear of the holder, and so that the sectionstshall project above the holder, and allow the corner and face of thestone to come clear down into the corners or angles formed bythesections. The holder G having been gauged to the required Obliquity,or'the stone havingbeen set, inclined, or dipped, by the rocking bearerC, and then clamped, or by bothI of these adjustments in part, thenecessary position of holder and stone having been attained, so as toget theIproper-grinding angle and bevel, the cutter-barand cutters areslid along in the recess s, and clamped by the clamps u u, and thenbrought to the action of lthe stone and ground. l

When the stone is adjusted, and its shaft retained so that it revolvesin a permanent' position, that is, without being fed np tothe sections,then, by means of the vset-screw q, the sections may be fed up with apositive unyielding motion 'to the stone, yto prevent jumping, andconsequent uneven wearing of theV stone. This is simply reversing thefeed-motion, and feeding up thc sections to the stone, instead of thestone to the sections, but in both cases the feedis rigid, 'for one andthe same purpose, viz, tocanse the stone' to wear true, and not out ofround, as is the case when not rigidly fed up and controlled. y

Having thus fully described our invention, vwhat we claim therein asnew, and desire to secure by Letters Patent, s-

1. In combination with the curved or hollowed-outblockB,the rocking andadjustable bearer c, for adjust'.

ing the shaft of theA grindstone, substantially as .and for the purposeset forth. Y

2. We also claim, in combination with the shaft D and its stone E, thecollar e and arm g, so that the stone may be fed and heldup to thesections by a'. positive and unyieldng feed, or' be held rigid by saidarm, substantially as land for the purpose described. l

3. We also claim` the combinationof the table or arcs I IA with thholder G, for guiding, holding, and gauging the'inclination of saidholder, by devices connected therewith, substantially as described.

' We also claim, in combination with a fixed position of rotation of thestone, the screw q, as a feedingscrew, to feed theisec'tion to the stoneand rigidly hold it against jar or motion, and thus prevent thestonefrom Wearing out of vround, substantially-,as described. v f
